Abstract:

【OBJECTIVE】The author plan to understand the soil compaction of land consolidation in loess Plateau area and formulate corresponding improvement measures to promote the optimal allocation and effective use of land resources【METHOD】The land consolidation project in Hougong Town Wenxi County was conducted in this paper, to investigate the soil bulk desity, compaction, the water content and infiltration rate. 【RESULT】The result showed:(1) In comparison with the general farmland soil, the soil bulk desity increased by 1.34 times and compaction increased by 484 times in land consolidation. (2)The rate of initial infiltration was 1.21mm/10min and the rate of steadily infiltration was 0.7mm/10min in compaction soil,was equal approximately to 16% and 28% in general farmland soil. 【CONCLUSION】These physical properties indicated that land consolidation area is very serious level of soil compaction, we must take appropriate measures to improve compaction of the soil, rapidly improving land productivity.
